SMA JMS-F-V2 SunSpec Rapid Shutdown Device

SMA JMS-F-V2 SunSpec Rapid Shutdown Module

The SMA JMS-F-V2 SunSpec Rapid Shutdown Module (MPN: SMA-JMS-F-V2) is a module-level rapid shutdown device (RSD) designed for photovoltaic (PV) solar panels up to 600W. It provides automatic rapid shutdown at the individual module level when the SunSpec rapid-shutdown signal is interrupted, helping solar installations satisfy NEC electrical safety requirements.

Communicating via Power Line Communication (PLC) over existing DC PV conductors, the unit requires no dedicated signal wiring, which streamlines array installation and reduces labor costs. Equipped with industry-standard MC4 connectors, it initiates rapid de-energization in 10 seconds or less to protect first responders and service technicians during emergency events.
